Two-phase stepper motor 60BHH100-300A-21A

NEMA 24high-torque

Product Overview
The 60BHH100-300A-21A is the highest-torque model in the 60BH series, delivering 2.94 N·m (30 kg·cm) in a 60 mm (NEMA 24) 100 mm body. This 2-phase 4-lead motor is the go-to choice when maximum holding torque is required within the 60 mm (NEMA 24) frame. Common applications include CNC routers, laser cutters and medium-duty industrial automation.

Key Highlights

• 2-phase, 1.8° step angle — 30 kg·cm (2.94 N·m) peak holding torque in NEMA 24
• 3.0 A/phase — rated current enabling maximum torque for 60 mm frame
• 100 mm body length — highest torque variant in the 60BH family
